I have setup an exchange box on my domain with the following
1-I am sending my emails using SMTP.com (we don't rely on our ISP).
2-Receiving emails - Internally I have no issues. but external emails are set up one-on-one with GoDaddy.
The domain name is hosted @GoDaddy. so I created a bunch of emails accounts (firstname.lastname@example.org,email@example.com et...)
and using a POP connector I am getting those emails in my exchange box who is then distributing them...
Now I have a problem. the problem is that my boss comes and tells me that he wants to create 400 emails addresses and he doesn't want to pay 14.4 USD * 400 /year for this.
Is there a way I could DDNS to solve the issue of me being tied up with my ISP ?
The whole setup is built upon me being able to change ISP in a snap.
(using Godaddy for incoming and retrieving them using POP connector - and sending using SMTP.com).
You ideas/suggestions are welcome as I have no idea how to setup Exchange with DDNS.
